In association with the Oceanographic Museum of Monaco, Hublot unveils a diver's watch able to withstand the pressure
exerted at a depth of 4,000 metres.
It is a symbolic watch. The 4000 m watch. A watch developed for pushing the limits of what is rational and possible. It has taken 18
months of research, development and testing to present, today, the Oceanographic 4000, a watch which can be worn on dives to depths
of 4,000 metres, under extreme pressure - an exceptional technical achievement.
For the first time, the famous Oceanographic Museum of Monaco, with the Institut Océanographique Fondation Albert 1st Prince de
Monaco - names renowned throughout the world in the fields of marine studies, research and conservation - has agreed to be associated
with a watch. Quite some symbol.
A genuine instrument with technology developed to the extreme, ergonomics for efficiency and ease of handling, this watch
was conceived and designed to push the limits of the possible.
Almost all the features of the Oceanographic 4000 are exceptional, in terms of design, development and manufacturing. To be described as
diver's watch, resistant to the pressure exerted at the record depth of 4,000 metres, the watch had to meet the exacting specifications of the
international standards of Swiss watchmaking (NIHS).
Starting with its seal, tested by Hublot in a Roxer tank, submerged and pressurised to the equivalent of 5,000 metres. To ensure the
watertightness of the watch and to resist this extreme pressure, the synthetic sapphire crystal is 6.5 thick. This is thicker than normal, but is
reasonable for this level of resistance. The case back is screw-down, a sine qua non for reaching such depths. It is made of grade 2 titanium,
an extremely strong stainless material.
As its case is made of King Gold (18K gold with 5% of platinum which gives this special intense red color), the Oceanographic 4000 is still light
on the wrist - although its diameter of 48 mm and its volume is substantial.
From the brightness standpoint, the time and elapsed time measured by the flange must be legible from a distance of 25 cm in the dark. To
meet this requirement, the dial, the flange and the hands of the Oceanographic 4000 have been optimised to have a larger surface area treated
with SuperLuminovaTM, a luminescent material emitting a white colour.
The reading method has been made as safe as possible, using an internal rotating flange which is unidirectional and rack-driven, with a dive
time indicator. The dive time indicator being placed as close as possible to the dial minimises the risk of inadvertently altering the dive time.
It also makes the dive time easier to read. In accordance with the standard, the Oceanographic 4000 has a minute scale on which the
five-minute periods are clearly highlighted.
The watch is fitted with two screw-down crowns (a protective measure that helps ensure water resistance by compression of an O-ring seal).
The flange crown which sets the dive time is placed at the 2 o'clock position for easy access and more comfortable use. It is unidirectional,
again for safety reasons, with a bayonet fitting and protected by an oversized crown guard, for extra safety and easy operation when handling
diving equipment. The second crown, for winding and setting the time and date, is positioned at 4 o'clock to avoid obstruction.
Finally, the Oceanographic 4000 has a helium valve, a feature essential to any diving watch capable of descending to great depths.An essential
feature when the watch is used in diving chambers, the helium valve allows gases that have infiltrated the watch during the descent to safely
escape during the ascent. The valve fitted to the Oceanographic 4000 is made of stainless steel, positioned at 10 o'clock, visible from the
left-hand side lug.
The watch comes with two tongue and buckle straps ("Town" & "Diver"). This type of fastening is more secure than a folding clasp for this type
of use, and is also easier to handle and close when using gloves. Note that the design of this buckle is original (because the use of a tongue is
rare in the normal Hublot collections) and that its method of attachment to the case is even more so with two small push buttons built into
each end of the case to allow the strap to be changed instantly without the use of a screwdriver or any other accessory. The "Town" strap is in
white rubber. The "Diver" strap, a blend of white rubber and NomexTM, longer than a standard strap, has been developed to be worn over a
diving suit up to 8 mm thick.
The Oceanographic 4000 has been designed to meet the most demanding requirements of both professional divers and watch
enthusiasts. It will enter the history of diving watches which have become legendary.
